XF 1.5Staff CSS & Configuration

Member

So, I am not sure how to find the Staff.CSS that this guide refers to. What I want to do is change the banner color of my current 'Staff Member' banner and, move it below their main tag(s). Right now it is above 'Administrator' and 'Owner' which I don't like. Any help is appreciated! Thanks!​

Thanks for a fast reply, but I don't quite see where to look in the second link for help on moving the positioning of banners ETC. My bad if I'm missing it, but could you be more specific on like what to add and where to add it, or point me to where that would be specified? (Which category in Broguide)
